Bakerlok Thread-Locking Compound replaces welding for locking casing joints on the bottom lengths to prevent unscrewing while drilling out cement. Welding of shoes, couplings, and collars to casing often weakens the casing and should be avoided wherever possible.
High Lubricity Tests were made using Bakerlok on one side of a standard coupling and API Modified thread dope on the other. Identical pin threads were made up into the coupling. For the same amount of torque, the joint with Bakerlok made-up furrher and was cooler than the joint not made up with Bakerlok.
